2x+y=8 is the equation perpendicular to x-2y=8.
9 plates x 15 cups = 135 total cups.
135 cups x 10 chocolate balls = 1,350 total.
Convert the milligrams into grams
1,000 milligrams = 1 gram
so 1.75 grams X 1 gram/1 gram = 1.75 X 1 = 1.75 grams
hope that helps :)
Do you know how to graph by finding the x and y intercepts? Or can you solve for y so your equation looks like y=mx+b?
Answer:
7f
r = ----------- - 4
z
Step-by-step explanation:
I will assume that you meant:
7f
z = ------------
r + 4
Solve for r. Start by interchanging z and (r + 4):
7f
r + 4 = -----------
z
Now subtract 4 from both sides. This isolates r:
7f
r = ----------- - 4
z
